Assembly Procedure

Note: Cleanliness is an important factor. Before the assembly procedure, the components should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.

Note: Check all the O-ring seals and the components for wear or damage. Replace the components, if necessary. Lubricate the O-ring seals lightly with the lubricant that is being sealed.
